The S5L8950 is the Apple A6 processor currently used in the iPhone 5 and iPhone 5c.
The processor supposedly uses custom Apple silicon.
The software architecture as reported by "hostinfo" is: armv7s.
Contents
Hardware
The A6 is a 32-bit processor with part number is APL0598. It is produced by Samsung with its low power 32nm CMOS process. The die has an area of 95mm². It incorporates a three core PowerVR SGX543MP3 GPU clocked at 266MHz.
Software
The chip contains Bootrom 1145.3. It runs ARM based instructions with the CPU Instruction set ARMv7s. The exact ARM reference has to be determined yet.
iBoot load address is 0x80000000, framebuffer for n41ap begins at 0xBF7AA000.
